我一直在尝试PreRender.Io在本地计算机上安装进行测试。我已经安装了Python 2.7.10。当我键入：

npm install prerender

它给出一个错误：

C:\PreRender\node_modules\prerender\node_modules\phantom\node_modules\dnode\node
_modules\weak>if not defined npm_config_node_gyp (node "C:\Program Files\nodejs\
node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js"
rebuild )  else (node  rebuild )

我找不到CL.exe，在Google上进行的快速搜索似乎缺少了一些Visual C 编译器。但是，我尝试安装说VC
2008可再发行的x86，但仍然是同样的问题。

知道有什么问题吗？操作系统是Windows 7 64位。
